Correlation between admitting blood glucose levels and H=hospital outcome in patients who underwent percutaneous coronary intervention

ABSTRACT

Objectives@#This study aimed to determine the correlation between admitting hyperglycemia and hospital outcome, on the length of hospital stay and mortality on patients who underwent PCI.@*Methodology@#A single center, retrospective observational study involving patients who underwent percutaneous coronary intervention (PCI). They were divided in four (4) groups according to presence of admission hyperglycemia (capillary blood glucose >140mg/dl) and presence of diabetes Group 1 (patients with diabetes with admission hyperglycemia), Group 2 (patients without diabetes with admission hyperglycemia), Group 3 (patients with diabetes without admission hyperglycemia), and Group 4 (patients without diabetes without admission hyperglycemia). Length of hospital stay and mortality outcome were compared between four groups and in-hospital mortality related risk factors were analyzed by binary logistic regression analysis.@*Results@#133 patients were included in the analysis, of which 50% have admission hyperglycemia. The length of hospital stay was significantly longer in patients with admission hyperglycemia (12 vs 9 vs 7 vs 7 days, p= 0.006). The mortality rate between 4 groups were non-significant (14% vs 10% vs 9% vs 11%, p=0.272). Multiple logistic regression analysis showed the following were associated with increased mortality in patients who underwent PCI age (odds ratio [OR] 1.1265, 95%CI 1.0497 – 1.2090, p=0.001), capillary blood glucose on admission (OR 1.0077, 95% CI 1.0015 – 1.0140, p= 0.015), presence of ST elevation on ECG (OR 16.5671, 95% CI 3.4161 – 80.344, p=<0.001).@*Conclusion@#An elevated admission capillary blood glucose, regardless of presence or absence of diabetes, was associated with longer length of hospital stay; however, it was not predictive of in-hospital mortality. Interestingly, patients with admitting hyperglycemia had earlier mortality.
